We present observations and analysis of the broad-band afterglow of Swift GRB071025. Using optical and infrared (RIYJHK) photometry, we derive a photometric redshift of 4.4 z 5.2; at this redshift our simultaneous multicolour observations begin at ~30 s after the gamma-ray burst trigger in the host frame, during the initial rising phase of the

During our detailed study of the kinematics of the know exoplanets hots stars (Montes et al. 2010, Caballero et al. 2010) we have identified possible members of the classical moving groups with ages between 10 and 600 Myr (e.g. Local Association, Castor, Ursa Majoris, IC 2391, Hyades). In order to constraint their actual youth and possible

The Fermi Large Area Telescope (LAT) discovered a new gamma-ray source near the Galactic plane, Fermi J0109+6134, when it flared brightly in 2010 February. The low Galactic latitude (b = -1fdg2) indicated that the source could be located within the Galaxy, which motivated rapid multi-wavelength follow-up including radio, optical, and X-ray

The effect of the Galactic Cosmic Ray (GCR) flux on Earth's climate is highly uncertain. Using a novel sampling approach based around observing periods of significant cloud changes, a statistically robust relationship is identified between the rate of GCR flux and the most rapid mid-latitude (60°-30° N/S) cloud decreases operating over daily

Light curves in the CoRoT white, blue, green, and red channels. The CoRoT bands are not simply related to any standard photometric systems. Because the applied corrections are channel-specific, the flux in the white channel is not the exact sum of the blue, green, and red fluxes. Also provided are the radial velocity measurements by the SOPHIE and

The 11-year activity cycle of the Sun is a consequence of a dynamo process occurring beneath its surface. We analyzed photometric data obtained by the CoRoT space mission, showing solarlike oscillations in the star HD49933, for signatures of stellar magnetic activity. Asteroseismic measurements of global changes in the oscillation frequencies and
